EURASIP Journal on Wireless Communications and Networking, 2007 A novel beamforming (BF) system that employs two switched beam antennas (SBAs) at both ends of the wireless link in an indoor double-directional radio channel (DDRC) is proposed. The distributed directivity gain (DDG) and beam pattern correlation in DDRC

A High-Capacity Reversible Data Hiding Scheme Using Dual-Channel Audio
IEEE Access, 2020 In recent years, the reversible data hiding (RDH) based on dual stego cover is developing rapidly because of its high capacity and low distortion. For image case, however, two consecutive images of the same image will draw the attention of adversaries ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Ergodic Capacity of Generalized Fading Channels With Mobility
IEEE Open Journal of Vehicular Technology, 2022 In this paper, we consider the ergodicchannel capacity (ECC) of several generalized fading channels for a mobile user that moves inside a coverage area according to the random waypoint (RWP) mobility model.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

User Effects on MIMO Performance: From an Antenna to a Link Perspective
International Journal of Antennas and Propagation, 2011 We investigate in this paper the effects of the user's presence on the performance of a multiple-input multiple-output (MIMO) system in data and in voice usage scenarios. The investigation studies the user effects on the antenna performance and how these

Capacity of the Energy Harvesting Channel with a Finite Battery
, 2016 We consider an energy harvesting channel, in which the transmitter is powered by an exogenous stochastic energy harvesting process $E_t$, such that $0\leq E_t\leq\bar{E}$, which can be stored in a battery of finite size $\bar{B}$. We provide a simple and
